Question:
I want to set up my NT Server as my primary domain server. How do I do it?
Answer:
Unfortunately, the only way I know to convert a current NT non-DC (i.e., not either a PDC or BDC) server into a PDC is to re-install. There are ways to convert a BDC into a PDC without re-installing, but I know of no way to do this for a non-DC server.
